INSECT- SPECIFICATION forming part of Letters Application filed April 25, 1902.

To (all whom it may concern:

Be it known that I, HENRY A. BIERLEY, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Insect-Trap; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

The object of this invention is to make an improved form of trap for flies and similar insects.

Broadly stated, the invention consists of a bait-cylinder horizontally mounted, with means to keep it rotating, and a casing with the lower part translucent, in which the lower part of the cylinder turns, so that the flies that gather on top of the cylinder to eat any bait placed thereon will continue thereon so by reason of the light below until they are carried into the casing and be unable to return. To attract the flies, the cylinder is made of bright tin or other bright and attractive material, and the bait is carried in 2 5 depressions in the cylinder. A second chamber beside the lower part of the cylinder is provided for the flies.

The exact nature of said invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a'plan view of the fiy-trap containing the features of my invention. Fig. 2 is an elevation of the left hand thereof. Fig. 3 is a vertical cross-sec- 3 5 tion through the device.

The fly-trap shown in the drawings consists of a cylinder 10, mounted horizontally in a stationary casing below and which supports the cylinder. The cylinder is carried on the 0 rod 11, that has bearings in the ends 12 of the casing. The ends 12 are made, preferably, of wood, and the sides and bottom of the casing are made of translucent wire-netting'13,"the' ends of which are bound to the ends 12 of the casing by the metal strips 14. The casing is supported upon legs 15, which hold it elevated. The cylinder is rotated in the direction indicated by the arrows by any suitable means, that shown being a spring-motor 16,

5o regulated by a clockwork mechanism form- TRAP.

ing a part thereof, which motor is old and common for actuating things, and the details thereof are not herein shown or described, as

this invention is not limited to any particular means for rotating the cylinder. The width of the casing is greater than the diameter of the cylinder, and only the lower half of the cylinder extends into said casing. There are two chambers in said casingthe outer or cylinder chamber 27, in which the cylinder rotates, and the inner chamber 17 for holding the flies coming from the outer chamber. These chambers in the casing are separated by a partition, the upper part of which is formed of a metal plate 18 and the lower part of wire-netting 19. The upper part or plate 18 is secured to a reinforcing horizontal bar 20, that extends from one side of the casing to the other for supporting the inturned upper edge of the wire-netting 13. 7o Said plate 18 is inclined downwardly somewhat toward the cylinder and has a guardplate 21, that extents toward the cylinder, so

as to prevent the flies from escaping from the chamber 27 in which the cylinder is mounted, but is spaced far enough from the cylinder to permit flies on the cylinder to pass it. Immediately below said guard'plate 21 there is a series of large openings leading from the outer chamber 27 to the inner chamber 17 through solid conical tubes 22, and through which flies may readily pass into said inner chamber. The tubes 22 face the translucent wall of the inner chamber on the right. The outer surface of the plate 18 is preferably made bright and the inner surface dark, and the conical tubes 22 being contracted at their inner ends the flies will not escape.

The chamber 27, in which the cylinder is mounted, is closed to hold the flies on one side by said guard-plate 21 and on the other side by the guard-plate 28, that approaches the cylinder very closely. Flies may enter the autechamber independently of the cylinder through a series of openings formed in 5 the bottom by the conical tubes 29. A door 30 is made in the end of the casing to give access to the chamber 17 for cleaning or for any other purpose.

In using the device it is preferably placed too near a window with the right-hand side, as shown in Fig. 3, next to the window. However, it can be used elsewhere. Syrup or other suitable bait is placed on the cylinder, preferably in the grooves 31. Vhen the motor is wound up, the cylinder will rotate in the direction indicated by the arrows and will carry the flies that alight upon the cylinder into the chamber 27. They will not fly away as they enter the chamber 27, because the plate 18 is bright, and the lower part of the partition 19, as well as the bottom of the easing, is made of wire-netting or other translucent material. After the fly enters the chamber 27 he cannot escape, as the guardplate 28 will prevent him from following the cylinder. If the fly goes in the other direction to the right, he will climb the wire-netting 19 in the partition between the chambers 27 and 17 until he reaches the guard-plate 21, whereupon he will move to the left and enter a conical tube 22, because its inner end faces the light, inasmuch as the right-hand side of the chamber 17 is formed of wire-netting or other translucent material. device is made in order that the flies may pass from the chamber 27 into the chamber 17, and it thereby increases the capacity of the device. Flies that crowd about the device and crawl under it will through the inlet-tubes 29, and thereby enter the chamber 27, being led to do so by the bright baited cylinder above said inlet-openings. By having the fly-chambers below the upper half or more of the top surface of the cylinder is exposed for flies to alight upon.
